BICYCLE AND TRICYCLE.

SPECIFICATION forming part of Letters Patent No. 697,104, dated April 8, 1902 Application filed July 27,1901. Serial No. 69,981. (No model.)

To all whom, it hwy concern:

Beit known that I, GUSTAV ADOLPH HEIN- RICH PIETSCH, a subject of the King of Great Britain and Ireland, residing at Kiata East, in the county of Lowan, State of Victoria, and Commonwealth of Australia,have invented certain new and useful Improvements in Bicycles and Tri'cycles, of which the following is a specification.

My invention relates to two or three wheeled machines in which the rider is propelled by the movements of the hands and the feet combined; and the objects-of my improvements are, first, to provide a machine enabling the arms, the legs, and the back to be all equally exercised; second, to furnish a combined rest and thrust pedal for the feet, which places the rider in as natural a position as though sitting in achair, and, third, to so construct the parts that the combination shall be light and easy-running.

Referring to the drawings which form a part of this specification, Figure 1 represents a side elevation of the propelling and steering parts of my invention with the frame and wheels removed. Fig. 2 is a plan with the handle-bar and pedal-cranks also removed. Fig. 3 is a side elevation of the machine complete. Fig. 4 is a front elevation, on an enlarged scale, of the pivot-pin, showing the enlarged middle, trunnions, lever, collar, and extensions thereon, and on the right-hand side the connecting-rod on the extension, the said rod being in section. Fig 5 is a plan of the collar, showing its extensions.

Similar letters of referenceindicate similar I or corresponding parts where they occur in the several views.

On reference to the drawings it will be seen that A is a reciprocating hand-lever, at the top of which are the handle-bars C. This lever is capable of two motions, a backward and forward,in the same plane as the machine, and an also partial rotary around its own axis. At its lower end it enters a removable ring or collar D, Fig. 4, which is secured to it by a screw or key of other means. On this collar, Fig. 5, which partially rotates with the hand-lever, are two extensions or arms E. The bottom of the lever passes loosely through and can turn in a hole in the top and bottom wheel M.

Z of the enlarged middle portion of'a transverse pivot-pin. The ends of the enlarged middle have extensions or trunnions F thereon, which partially rotate in bearings in the frame of the machine and overhang the said bearings. Through the enlarged middle of the pivot-pin is a rectangular-sectioned slot A to admit the entrance of the collar D, which is inserted in the slot before the bottom of the hand-lever is passed through. To each overhanging trunnion is attached a crank-arm G, the angle of which (with the hand-lever) may be varied. At the bottom of each arm is a combined rest and thrust pedal H.

To the back of the leverA and retained vertically by the vertically-adj ustable collars S is intermediately pivoted the front end of the connecting-rodK. The rear end of this is pivoted to the pin L on the front sprocket- This pin is adjustable radially in a slot, thereby permitting a variation in the travel of the hand-lever. The spindle N, carrying said sprocket-wheel, rotates in a bearin g beneath the frame of the machine. From the front sprocket-wheel a chain 0 leads to and drives the rear sprocket-wheel, which turns the rear or driving wheel or wheels of thereto the rear ends of connecting rods or wires P. The front ends of these are connected to a motion-carrying cross-bar Q, pivoted at R to a bridge across the front of the machine-frame. From this cross-bar the rear ends of the connecting-rods P are pivoted, and the front ends of the said rods are pivoted to the extensions T of the front axle.

The saddle is supported on spiral springs, which in turn rest upon a carriage V. At the side of or beneath this carriage are four wheels W, (two upon each side,) which rest upon the two top tubes X of the frame. To retain the carriage on the tubes, a retaining-strap Y passes underneath the said tubes. If desirthe pedals.

himself with his hands and thrusts the pedals out with his feet. The saddle responds to this action, and on the return stroke the lever is pushed forwardly and the feet are moved backwardly.' The connecting-rod at the back of the lever thereby turns the front sprocketwheel, and the steering is effected by the rider slightly turning the handle-bar in the direction required. The riders feet are always at rest and never have to be lifted, as on the upstroke of rotating-pedal machines, and by my arrangement of parts he can exert all his strength without unduly straining or fatiguing any particular muscles or limbs.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is v v 1. The combination of the frame, the steering-wheel, a hand-lever in rear of said wheel, a collar 011 the lower end thereof, a cross-bar pivoted behind said wheel, linkconnection between said collar and cross-bar, and con-- nections between the said cross-bar and the steeringwheel shaft, whereby the latter is steered by and from said lever, substantially as described.

. 2. The combination of the frame, and front I and rear wheels, a rock-shaft journaled in the the front wheel from and by said lever, all substantially as and for the purpose described.

The combination of the frame, a steering-wheel, a rotatory and reciprocating handlever in rear of said wheel, a collar on the lower end of said lever, a cross-bar pivoted behind said wheel, links connecting opposite sides of the collar with said cross-bar at opposite sides of its pivot, and rods connecting the outer ends of said cross-bar with opposite ends of the steering-wheel shaft, all substantially as described.

4:. The combination of the frame and front and rear wheels, a rock-shaft journaled in the frame, a lever rotatably connected to said shaft having a collar on its lower end, and pedals on opposite ends of said shaft, a gear journaled in rear of the lever, a pitman for actuating said gear from said lever, and means for driving the rear wheel from said gear; with an oscillating cross-bar in front of the rock-shaft, links connecting said bar to pins attached to opposite sides of the collar on said lever, and rods connecting the outer ends of said cross-bar to opposite ends of the steering-wheel shaft, all substantially as and for the purpose described.

In witness whereof I have set my hand to this specification in the presence of two wit- DGSSES.
